[0002] An EPG (electrical program guide) is a commonly used and important function of a digital television device, and an EPG system can quickly find a program required by a user from a large number of digital television programs. Program information processed by the EPG system is referred to as EPG information. The EPG information stored in the digital television device is limited, and if more EPG information is to be obtained, the EPG information needs to be updated. The updating of the EPG information depends on a tuner. Generally, the tuner is occupied by a frequency point of a currently played channel, and the tuner can only update EPG information of the current channel and cannot update EPG information of a channel that is not currently played. With the progress of technology, many digital televisions are configured with double tuners to simultaneously work for live broadcast and recording. However, when one tuner is occupied, the other tuner is generally idle and still cannot update EPG information of other channels. The updating of EPG information of all channels is usually performed at night, which leads to that the EPG information is not updated in time and the user cannot immediately obtain the latest EPG information.

[0027] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0028] Embodiment one

[0029] With reference to Figure 1 The embodiments of the present application provide an EPG information updating method applied to a terminal with multiple tuners. In a first embodiment of the EPG information updating method, the EPG information updating method comprises the following steps.

[0030] In step S10, channel list information of the terminal is acquired according to a preset updating period, and EPG information of each channel in the channel list information is detected for updating.

[0031] In step S20, if a channel whose EPG information needs to be updated is detected, the channel is taken as a to-be-updated channel.

[0032] In the embodiment, it needs to be noted that in the present application, the terminal further comprises an EPG scanning module and a database module, the channel list information is stored in the database module of the terminal, when the preset updating period is reached, the EPG scanning module of the terminal acquires the channel list information from the database module, determines channel information of a channel through the channel list information, and then finds EPG information of the channel information in the database module according to the channel information, and then detects whether the EPG information of the channel needs to be updated.

[0033] In addition, it also needs to be noted that the preset updating period is used to periodically detect whether all channels of the terminal need to be updated, the channel list information comprises all channels of the terminal and channel information of all channels, the channel information comprises channel name, channel number and channel frequency point information, the EPG information comprises channel program list and channel program duration, and the to-be-updated channel represents that a to-be-played duration of EPG information is less than a preset to-be-played duration.

[0034] In step S30, if at least one tuner in the terminal is idle, EPG information of the to-be-updated channel is updated based on the idle tuner, and EPG updating information of the to-be-updated channel is obtained.

[0035] In the embodiment, it needs to be noted that the tuner is used to update the EPG information, and the EPG updating information comprises updated programs and updated duration.

[0036] As an example, the steps S10 to S30 include: acquiring channel list information of the terminal according to a preset update period, detecting all channels of the terminal, judging whether EPG information of each channel needs to be updated, to determine a channel to be updated; judging whether a tuner of the terminal is idle, if at least one tuner of the terminal is idle, updating EPG information of the channel to be updated based on the tuner, to obtain EPG information of the channel to be updated.

[0037] If it is detected that all the tuners are occupied, the updating of the channel to be updated is stopped, the updating of the channel to be updated can be started after it is detected that a tuner is idle, or the updating of the channel to be updated can be performed when the next preset update period comes.

[0038] In addition, in the present application, the tuners can be detected when the terminal is in a live TV state or a standby state. Generally, when the terminal has two tuners, when the terminal is in the live TV state, one of the tuners of the terminal is usually occupied and the other is idle, and at this time, the idle tuner can be used to update the channel to be updated. When the terminal is in the standby state, the tuners of the terminal are all idle, and at this time, the two tuners can be used to simultaneously update the channel to be updated of the terminal, so that the updating efficiency of the EPG information is improved and the energy consumption of the terminal is reduced.

[0039] The embodiment of the present application realizes that even if a channel is not currently played on the terminal, the channel can be updated and detected, and when the channel needs to be updated, the EPG information of the channel is updated by using an idle tuner, so that the tuners are fully utilized. For a terminal having multiple tuners, when one tuner is occupied but the other tuners are not occupied, the idle tuners can be used to update the EPG information of the channel to be updated. The terminal does not need to wait until all the tuners are not occupied to update the channel to be updated. The updating efficiency of the EPG information and the timeliness of the EPG updating are improved, and the user experience is improved.

[0040] The step of updating and detecting the EPG information of the channel includes:

[0041] Step A10: determining channel information of the channel according to the channel list information of the terminal;

[0042] Step A20: matching EPG information of the channel in EPG storage information of the terminal according to the channel information of the channel, and detecting whether the EPG information of the channel needs to be updated.

[0043] In the embodiment, it is to be explained that the EPG storage information is the EPG information of all channels stored in the database module by the terminal, and the EPG storage information comprises the channel name, channel number and EPG information of all channels, and the channel information comprises the channel name, channel number and channel frequency point information, and the EPG information of the channel is searched in the EPG storage information according to the channel name and channel number.

[0044] As an example, the steps A10 to A20 comprise: determining the channel information of the channel according to the channel information; matching the EPG information of the channel in the EPG storage information based on the channel name of the channel number of the channel information, and detecting the EPG information of the channel; if it is detected that the EPG information of the channel does not need to be updated, detecting the EPG information of the next channel in the channel list information; if it is detected that the EPG information of the channel needs to be updated, taking the channel as a channel to be updated. Wherein, whether the EPG information of the channel needs to be updated can be detected by the EPG scanning module of the terminal.

[0045] The embodiment determines the channel information of each channel, matches the EPG information of the channel in the EPG storage information according to the channel information, and then detects whether the EPG information of the channel needs to be updated. By detecting the update of all channels of the terminal, the update of the channel not played by the current terminal can be detected, the EPG information of the channel is updated when it is detected that the channel needs to be updated, the timeliness of the channel update is improved, and the EPG information of the channel is obtained in the database storage module of the terminal and then updated, so that whether the EPG information of the channel needs to be updated is detected without using the frequency modulator, the channel whether needs to be updated can be detected when the frequency modulator is occupied, and the efficiency of detecting the channel update is improved.

[0046] The step of detecting whether the EPG information of the channel needs to be updated comprises:

[0047] Step B10, judging whether the to-be-played duration of the EPG information of the channel is less than or equal to a preset to-be-played duration;

[0048] Step B20, if it is judged that the to-be-played duration is less than or equal to the preset to-be-played duration, determining that the EPG information of the channel needs to be updated;

[0049] Step B30, if it is judged that the to-be-played duration is greater than the preset to-be-played duration, determining that the EPG information of the channel does not need to be updated.

[0050] In the embodiment, it is to be explained that the to-be-played duration represents a total playing duration of channel programs in the EPG information of the channel after a current time point, and the preset to-be-played duration represents a critical to-be-played duration for determining that the EPG information of the channel does not need to be updated.

[0051] As an example, the steps B10 to B30 include: determining whether the to-be-played duration of the EPG information of the channel is less than or equal to a preset to-be-played duration, if it is determined that the to-be-played duration is less than or equal to the preset to-be-played duration, the EPG information of the channel needs to be updated, and if it is determined that the to-be-played duration is greater than the preset to-be-played duration, the EPG information of the channel does not need to be updated. Wherein, when it is determined that the EPG information of the channel needs to be updated, the channel is taken as a to-be-updated channel, and when it is determined that the EPG information of the channel does not need to be updated, the EPG scanning module of the terminal continues to detect channels that have not been detected whether to need to be updated according to the channel list information.

[0052] The embodiment of the application determines that the EPG information of the channel needs to be updated when the to-be-played duration is less than the preset to-be-played duration, so that the total playing duration of channel programs in the EPG information of the channel can be updated in time, and the total playing duration of to-be-played channel programs in the EPG information of the channel is avoided from being insufficient to provide programs for the channel when the channel needs to play, so that the EPG information of the channel needs to be reacquired, and user experience is reduced. Therefore, whether the to-be-played duration needs to update the EPG information of the channel can improve the timeliness of updating.

[0053] Embodiment Two

[0054] Further, with reference to Figure 2 , based on the above-mentioned embodiments of the application, in another embodiment of the application, the same or similar contents as the above-mentioned embodiments can be referred to the above introduction, and the following will not be described in detail. On this basis, based on the idle tuner, the EPG information updating method further includes the following steps before the step of updating the EPG information of the to-be-updated channel to obtain the EPG updated information of the to-be-updated channel:

[0055] Step C10, determining whether the idle number of the idle tuner is less than a preset idle number;

[0056] Step C20, if the idle number of the idle tuner is equal to the preset idle number, sending the channel frequency point information of the to-be-updated channel in the to-be-updated channel frequency point information of the to-be-updated channel frequency point information to the tuner;

[0057] Step C30, if the idle number of the idle tuners is greater than the preset idle number, sending the channel information of each of the to-be-updated channels of the to-be-updated channel information to each of the idle tuners, wherein the idle tuners correspond to the channel frequency point information of the to-be-updated channels one by one.

[0058] In the embodiment, it is to be noted that the preset idle number can be set by the user. In the present application, the number of tuners of the terminal is 2, and the preset idle number can be 1. When the idle number of the tuners is 1, the channel information of the to-be-updated channels is sent to the tuners, wherein the channel information includes channel frequency point information. When the idle number of the tuners is greater than 1, the channel information of each of the to-be-updated channels of the to-be-updated channel information is sent to each of the tuners. The tuners can only lock one channel frequency point information at a time. After the EPG information of the channel corresponding to the frequency point information is updated, the next to-be-updated channel frequency point information is received. When the idle number of the tuners is 0, it is indicated that the terminal currently has no idle tuners. When the idle number of the tuners of the terminal is 2, the terminal can simultaneously update the EPG information of two to-be-updated channels, thereby accelerating the channel updating efficiency of the terminal and reducing the energy consumption of the terminal.

[0059] As an example, steps C10 to C30 include: judging whether the idle number of the idle tuners is greater than a preset idle number; if the idle number of the idle tuners is equal to the preset idle number, sending the channel information of the to-be-updated channels to the idle tuners; if the idle number of the tuners is greater than the preset idle number, sending the channel information of each of the to-be-updated channels to the tuners; and if the idle number of the idle tuners is less than the preset idle number, not sending the channel information of the to-be-updated channels to the idle tuners. When the idle number of the idle tuners is less than the preset idle number, it is indicated that the terminal currently has no idle tuners.

[0060] The embodiment realizes the updating of the EPG information of the to-be-updated channel even when the terminal is in live television program (when one of the tuners is occupied), and fully utilizes the tuner resources. Further, when both of the tuners of the terminal are in the idle state and the preset updating period is reached, the two tuners can simultaneously update the to-be-updated channel in the to-be-updated channel information, improve the updating efficiency of the to-be-updated channel, and reduce the energy consumption of the terminal. In the present application, even when the terminal is in the standby state in the preset updating period, the idle number of the tuners can be detected, and the updating detection and updating of all channels of the terminal can be performed.

[0061] The step of updating the EPG information of the to-be-updated channel based on the idle tuner to obtain the EPG updating information of the to-be-updated channel includes:

[0062] Step D10, sending the channel frequency point information of the to-be-updated channel to the tuner;

[0063] Step D20, frequency point locking the to-be-updated channel based on the idle tuner and the channel frequency point information, and detecting whether the to-be-updated channel is locked successfully;

[0064] Step D30, obtaining the to-be-played data of the to-be-updated channel after the to-be-updated channel is successfully locked;

[0065] Step D40, parsing the to-be-played data to generate the EPG updating information of the to-be-updated channel.

[0066] In the embodiment, it should be noted that the channel frequency point information includes channel frequency, channel symbol rate, and channel bandwidth, and the channel frequency point information is used to provide frequency locking information for the tuner, that is, the to-be-updated channel information is frequency-locked in the tuner. The terminal further includes an FE (Frontend) module 4, and the EPG scanning module 1 of the terminal sends the channel frequency point information to the tuner through the FE (Frontend) module 4 and performs frequency locking according to the channel frequency point information. The to-be-played data of the to-be-updated channel is obtained by the multiplexer module of the terminal after the to-be-updated channel is successfully frequency-locked, and the PSI (Program Specific Information) module 3 parses the to-be-played data to obtain the EPG updating information, wherein the EPG updating information is the to-be-played program sorted by the broadcast time, and the broadcast duration is the preset updating duration.

[0067] Referring to Figure 3 , the terminal comprises an EPG scanning module 1, a database module 2, a tuner module 6, a demultiplexer (Demux) module 5, a PSI module 3 and an FE module 4; the EPG scanning module 1 is in communication connection with the database module 2, the PSI module 3 and the FE module 4 respectively, the PSI module 3 is in communication connection with the demultiplexer module 5, and the FE module 4 is in communication connection with the tuner module 6; in combination with the description of the embodiments of the present application, the EPG scanning module 1 can be used to detect whether the EPG information of the channel of the terminal is updated; the database module 2 is used to store the channel list information of the terminal and the EPG information of all channels of the terminal, that is, EPG storage information; the tuner module 6 is used to update the EPG information, the demultiplexer module 5 is used to obtain to-be-played data; the FE module 4 is used to send the channel frequency point information of the channel to the tuner and is also used to lock the frequency of the tuner according to the channel frequency point information, and the PSI module 3 is used to parse the to-be-played data. The tuner module corresponds to a physical tuner device, and there are two tuners in the scene of double tuners. The demultiplexer is a TS (Transport Stream, transport stream) data channel component on the software. Each tuner is associated with a TS channel, and each TS channel is associated with a group of demultiplexers.

[0068] As an example, steps D10 to D30 include: determining the channel frequency point information of the to-be-updated channel according to the to-be-updated channel information, sending the channel frequency point information of the to-be-updated channel to the tuner; locking the to-be-updated channel in the tuner based on the tuner and the channel frequency point information, obtaining to-be-played data of the to-be-updated channel after the to-be-updated channel is successfully locked; and parsing the play data to obtain the EPG update information of the to-be-updated channel.

[0069] After determining the EPG information of the to-be-updated channel, the remaining to-be-updated channels in the to-be-updated channel information will continue to be updated until the EPG information of all to-be-updated channels in the to-be-updated channel information is completely updated. In this embodiment, the channel frequency point information of the to-be-updated channel is sent to the tuner, and then the frequency of the to-be-updated channel is locked, and the EPG information of the to-be-updated channel is updated after the frequency is successfully locked, thereby ensuring the accuracy of the update of the to-be-updated channel.

[0070] The step of detecting whether the to-be-updated channel is successfully locked includes:

[0071] Step E10, detecting whether there is a lock frequency signal of the to-be-updated channel in the idle tuner;

[0072] Step E20, if the frequency-locked signal of the to-be-updated channel exists in the idle tuner, it is determined that the to-be-updated channel is successfully locked;

[0073] Step E30, if the frequency-locked signal of the to-be-updated channel does not exist in the idle tuner, the to-be-updated channel is unsuccessfully locked, and the step of locking the to-be-updated channel in the tuner according to the idle tuner and the channel information is returned.

[0074] In the embodiment, it is to be noted that before the EPG information of the to-be-updated channel is updated by the frequency tuner, the channel frequency point information of the to-be-updated channel needs to be locked in the idle frequency tuner, so as to update the EPG information of the to-be-updated channel. The frequency-locked signal is used to detect whether the to-be-updated channel is successfully locked in the idle frequency tuner, and the frequency-locked signal can be an RF signal.

[0075] As an example, the steps E10 to E30 include: detecting whether the frequency-locked signal of the to-be-updated channel exists in the idle tuner; if the RF signal is detected, it is determined that the to-be-updated channel is successfully locked in the tuner; if the RF signal does not exist or is unstable, it is determined that the to-be-updated channel is unsuccessfully locked, and the step of locking the to-be-updated channel in the tuner according to the tuner and the channel information is returned. The to-be-updated channel is relocked. In the embodiment, the frequency-locked signal is used to determine whether the channel frequency point information of the to-be-updated channel is successfully locked in the frequency tuner, and the to-be-updated channel is relocked when the channel frequency point information of the to-be-updated channel is unsuccessfully locked, so as to ensure the accuracy of locking the to-be-updated channel.

[0076] After the step of analyzing the to-be-played data and generating the EPG update information of the to-be-updated channel, the EPG information updating method further includes:

[0077] Step F10, determining whether the update duration of the EPG update information satisfies a preset update duration;

[0078] Step F20, if the update duration is greater than or equal to the preset update duration, the EPG update information is stored in the terminal, and the to-be-updated channel is unlocked in the tuner;

[0079] Step F30, if the update duration is less than the preset update duration, the EPG update information is stored in the terminal after a preset waiting duration, and the to-be-updated channel is unlocked in the tuner;

[0080] In the embodiment, it is to be explained that the preset update duration is the shortest total duration of programs of channel update, the update duration is the total duration of programs in the EPG update information, the EPG update information is generated after the EPG information is updated, and the EPG update information is stored in the database module of the terminal. The preset waiting duration represents that when the update duration does not meet the preset update duration, the idle tuner continues to receive the EPG update information. When the EPG information of the update terminal channel is updated, the playing duration of the obtained to-be-played data does not necessarily meet the preset update duration. When the playing duration does not meet the preset update duration, the tuner waits for a preset waiting duration. If the update duration of the EPG update information still does not meet the preset update duration after the preset waiting duration, the EPG update information is stored to the terminal.

[0081] As an example, steps F10 to F30 include: judging whether the update duration of the EPG update information meets the preset update duration; if the update duration meets the preset update duration, storing the EPG update information in the database module of the terminal, and releasing the lock of the to-be-updated channel on the tuner; and if the update duration does not meet the preset update duration, storing the EPG update information to the terminal and releasing the lock of the to-be-updated channel on the tuner after a preset waiting duration.

[0082] In the present application, the idle tuner can only update the EPG information of one to-be-updated channel at a time. When the EPG information of the to-be-updated channel is updated, the to-be-updated channel is regarded as an updated channel, and the channel frequency point information of the next to-be-updated channel is selected from the to-be-updated channels and sent to the idle tuner. Then, the step of performing frequency point locking on the to-be-updated channel based on the idle tuner and the channel frequency point information of the to-be-updated channel, and detecting whether the to-be-updated channel is successfully locked is executed. After the to-be-updated channel is successfully locked, the to-be-played data of the to-be-updated channel is obtained. The to-be-played data is parsed to generate the EPG update information of the to-be-updated channel. Until all to-be-updated channels are updated.

[0083] In the embodiment, whether the update duration meets the preset update duration is judged. After the update duration meets the preset update duration, the EPG update information is immediately stored to the terminal, and the update of the next to-be-updated channel is continued, so that the update efficiency is improved. When the update duration is less than the preset update duration, the preset waiting duration is waited for, and the tuner does not continue to update other to-be-updated channels.
